DaMeatMan, thank you for all of your info.My only problem remains the same: i'm not sure that i will be able to get direct signal.Everything is placed on a balcony which has open front but covered top.It's just second floor and moving it outside isn't in my power.
My house is sort of low compared to highrises at the front, which faces Buffalo, and CN Tower is at the back where even closer buildings are.Seems that all i will get is off/in between buildings and that can't be stable all the time.
Seems that you have quite clear view and antenna isn't main factor.
